Abstract: The present invention is a radio frequency and digital signal dual carrier multiple modulation system that includes a transmitter system with digital components that include digital inputs, carrier signal sources, a multiplexer and logic controlled radio frequency switches that produces modulated signals and radio frequency components that includes radio frequency signal input and a radio frequency variable gain amplifier. There is also a receiver system with digital components that include a demultiplexer, buffer amplifiers, detectors, comparators and digital signal outputs that receive modulated signals from the transmitter system and radio frequency components with another radio frequency variable gain amplifier that receives the radio frequency output from the transmitter system and produces an amplified radio frequency output.

Abstract: Disclosed is an insult-sensing absorbent article including an absorbent assembly, an insult-sensing means coupled to the absorbent assembly, and a tuned antenna system coupled to the insult-sensing means. Also disclosed is a method for indicating an insult to an absorbent article to be worn by a wearer, the method including providing an absorbent article including a conductive element; providing an antenna system associated with the absorbent article, the antenna system including a signal generator and an antenna, wherein the antenna includes the conductive element, and wherein the antenna system is adapted to transmit a signal; and maximizing the receivability of the signal by optimizing an aspect of the antenna system.
